Su Qingran, who accidentally entered a closed Miao village, wanted to use the knowledge from her past life to improve the lives of the villagers. However, while collecting medicine, she unexpectedly met Lin Yuan, a 19-year-old Gu master in the village. The black figure shrouded in the mist and those cold pool-like eyes became a lingering shadow on her.
A warning Gu egg suddenly appeared, forcibly binding the two of them. Lin Yuan's voice reached his mind through the Gu eggs, and the cold command carried a force that could not be resisted: "Keep an eye on those outsiders, your life is in my hands." Su Qingran was forced to become his "eyes", and with vigilance and curiosity, she witnessed the mysterious power of this young Gu master to control the insect swarm, and also glimpsed the paranoia and loneliness behind his cold appearance.
The intrusion of explorers broke the peace in the village. After a frightening night caused by the insect swarm, Lin Yuan actually protected her behind him in front of everyone. The words "she is the one I protect" quietly changed the bond. The Gu eggs convey each other's emotions, they are his clumsy protection, they are her heartbeat moment, and they are also the fate that they cannot escape.
In the mists and secrets of Gu magic in the Miao village, an entanglement that began with coercion is slowly heading towards a two-way sinking.
